james.maesandClaude Sonnet 5.5 e4639e3cca chore: integrate printing standards and strict Java compiler checks
Preserve current rendering, operator and retained-source behavior while integrating script quality, meaningful headers and strict Error Prone/NullAway contracts. Production and test compilation and the 189-case verification gate pass with zero failures and one intentional workload skip.
